'Runway Roadkill' rapidly increasing at airports across the world, UCC study finds
The number of reported collisions (i.e. strikes) between aircraft and wildlife is increasing globally, with consequences for personnel and passenger safety as well as for industry economics. These are important considerations for airport operators that are obliged to mitigate wildlife hazards at airfields. Incidents involving mammals account for approximately 3-10% of all recorded strikes. However, relatively little research has been conducted on mammal strikes with aircraft outside of the USA.

More mammals are being struck by aircraft each year
Investigators have published a global review of mammal strikes with aircraft, noting that events have been increasing by up to 68% annually. More mammals were struck during the landing phase of an aircraft's rotation than any other phase, according to the article published in Mammal Review. (2021-02-03)

Turbulence model could enhance rotorcraft, munitions performance
Design of Army aerial vehicles and weapon systems relies on the ability to predict aerodynamic behavior, often aided by advanced computer simulations of the flow of air over the body. High-fidelity simulations assist engineers in maximizing how much load a rotorcraft can lift or how far a missile can fly, but these simulations aren't cheap. A new turbulence model could change that (2021-01-25)

Tiny particles that seed clouds can form from trace gases over open sea
New results from an atmospheric study over the Eastern North Atlantic reveal that tiny aerosol particles that seed the formation of clouds can form out of next to nothingness over the open ocean. The findings will improve how aerosols and clouds are represented in models that describe Earth's climate so scientists can understand how the particles--and the processes that control them--might have affected the planet's past and present, and make better predictions about the future.

A standout superalloy
In recent years, it has become possible to use laser beams and electron beams to ''print'' engineering objects with complex shapes that could not be achieved by conventional manufacturing. The additive manufacturing (AM) process, or 3D printing, for metallic materials involves melting and fusing fine-scale powder particles -- each about 10 times finer than a grain of beach sand -- in sub-millimeter-scale ''pools'' created by focusing a laser or electron beam on the material.

Military flights biggest cause of noise pollution on Olympic Peninsula
A University of Washington study provides the first look at how much noise pollution is impacting the Olympic Peninsula. The paper found that aircraft were audible across a large swath of the peninsula at least 20% of weekday hours, or for about one hour during a six-hour period. About 88% of all audible aircraft in the pre-pandemic study were military planes. (2020-12-07)

Keyhole wasps may threaten aviation safety
Over a period of 39 months, invasive keyhole wasps (Pachodynerus nasidens) at the Brisbane Airport were responsible for 93 instances of fully blocked replica pitot probes - vital instruments that measure airspeed -- according to a study published November 25 in the open-access journal PLOS ONE by Alan House of Eco Logical Australia and colleagues. As noted by the authors, the results underscore the importance of risk-mitigating strategies, such as covering pitot probes when aircraft arrive and setting up additional traps to intercept the wasps.
